RE: Need help with code by Reaper on 09-05-2005 at 03:36 PM

umm, how :P


RE: Need help with code by Stigmata on 09-05-2005 at 03:45 PM

#include <Gdi32.lib>


RE: Need help with code by Reaper on 09-05-2005 at 03:48 PM

Gdi32.lib: No such file or directory.

8-)

#pragma comment(lib, "gdi32.lib")

It's not a header :P

That'll work ;)
Or, if you're using Visual C++6, open the Project Settings (Alt+F7), go to the Link tab, and add 'gdi32.lib' to the end of the list (for all configs btw).

nop dont work. its odd, without using gdi32.lib in visual c++it works. but dev c++ doesnt work with or without it in
RE: Need help with code by RaceProUK on 09-05-2005 at 08:25 PM

It works in VC++ because that automatically links to gdi32.lib - it's a default. And that #pragma is specific to C++ as well - other preprocessors will have different ways of linking.

I see Dev-C++ uses a port of GCC. In that case, you'll need to find the command line and add '-lgdi32' to it.
